Pics for an 88 scirocco.
- EC36p35 -- input to BOSCH008 module (1.0ms charge time helps)
- Std IAT, CLT, TPS pinouts
- Knock senor currently hooked to E18p2,3 Hence why I have to check the wiring as per built.
- Trigger uses 5v out, analog ground, and Primary trigger in.
Here are two layouts. (can you upload the pics to FileArea and correct links ? The squirrelpf.com link seems to be gone!)
I'll have to create new ones.
Im using the fuel injection system
and the DummyIgnition
This shows the vehicle wiring mods
This shows connecting the GenBoard up
The question of the day is what is the output pin for DummyIgnition?
On GenBoard v2.2 the same output as used for DocsAndFAQ/EDISFAQ? (but EDIS requires different config.ign_out setting, of course), namely the MISC output, controlled from PORTB7 (inverted by a 800mA NPN). This is determined by ign_activate() in edis.c, defaults are IGN_PORT=PORTB IGN_DDR=DDRB and IGN_OUT=7 and can be overriden with my_make. Look at the setup of the old boys, eg: MembersPage/ChrisGerhardt
Translated for the non-enigneers's:
You have to change the type of output from the EDIS type to a type that will drive the Bosch 008 module.
the MISC output is mapped to pin 12 on the DB37 connector ie the SAW for the EDIS.
The output driver type is set in edis.h to be
IGN_PORT = PORTB
IGN_DDR = DDRB
ING_OUT = 7
These valuse can be changed in mymake so when you compile the firmware its set to the new output type for
Assuming that a hack is made for a WOT output.
it will drive a relay either switched ground or Switched 12v.
That relay at WOT will trigger the Nitrous system. ( 1 fuel, 1 nitrous solenoid )also as a quick addition, I got a water injection system from a member of the Scirocco list, and Brett my racing buddy thought, you know what else will work for water injection? The cold start valve. Excellent. Its got plumbed into the homebrew Home Depot intake. Remember Im on a budget, and out of time.
